I'm a web dev by day so playing around with Unity has been really fun. Having to consider time, i.e. what does everything like at time t=0, t=1, etc., adds a new dimension I don't get it my day job.
It's not programming but playing around with Blender has been really fun too.
I hear you. I come from a web dev background too and co-created A-Frame (https://aframe.io/) 8 years ago taking some of the Unity ideas (entity component) while retaining the fun parts of Web deving and publishing. Games and 3D graphics is super deep. Joy for me is having always interesting areas to explore that are not just the accidental complexity of the regular Web dev tooling.
